Microwave sensor cooking results are poor (overcooked or undercooked food) without showing an error code.

Safety: Unplug before cleaning near the sensor opening.

Steps:

• 1. Deep clean: Thoroughly clean the interior, especially near the sensor vent or opening, using mild detergent. Dry completely.
• 2. Follow instructions: Use recommended containers and coverings for sensor cooking per the Sharp manual.
• 3. Compare manual mode: If manual timed cooking works correctly but sensor modes do not, the sensor may be drifting.

Advanced: A technician can replace the humidity sensor with a Sharp part if cleaning does not restore proper operation.
